Utilization of oil (dissolved) of associated gas continues to be an extremely important issue for our country the last two decades. «Hitched» (so-called associated gas oil) – is a required element that accompanies the process of oil production and the presence of any oil, and especially gas and oil and gas condensate field. In fact, it is a gas that is released from the oil during its production. During this period, Russia ranks first in the world in terms of the burning of associated gas flaring at oil. Most of the free, especially low-pressure gases are classified as fatty and extra fat. With light oil is typically extracted more fatty gases, with heavy oil – mostly dry (lean and mean) gases. With the increase in C3+ hydrocarbons increases the value of the associated petroleum gas. Unlike natural gas, which has in its composition to 98% methane, the scope of the gas is much broader. After all, this gas can be used not only to produce thermal or electric energy, but also as a valuable raw material for petrochemical. The product range, which is possible to obtain a physical separation, is quite wide of associated gas: dry stripped gas (DSG); broad fraction of light hydrocarbons (NGL); stable natural gasoline; gas motor fuel (automotive LPG); liquefied petroleum gas (LPG) for domestic needs; ethane and other narrow fractions, including individual hydrocarbons (propane, butanes, pentanes).
Addition of APG can be separated nitrogen, helium, sulfur-containing compounds. It should be noted that at each subsequent process where the feedstock will be products of the previous stage (eg. Ethane → ethylene → polyethylene → plastic products, etc.), the value of new products will increase many times.
Despite the attractiveness of the utilization of associated gas in the industrial and commercial purposes, there are certain technical difficulties associated with some features of this raw material. While stressing the multi-stage separation of oil from the field associated gas should be prepared for transportation to the consumer.
In this article the need to address the utilization of associated petroleum gas due to environmental and financial considerations.
Currently, industry and housing and public utilities exert the main pollutant impact on surface-water bodies. At the same time, more than 90% of the total mass of pollutants released into water bodies from wastewaters are caused by chemical and petrochemical industry. At a petrochemical complex of Bashkortostan republic, Russia, producing the terephthalic acid and polyethylene terephthalate an environmental management system is implemented, so that it helps to maintain the composition of wastewater and discharges into the atmosphere within the maximum allowable concentrations.
